I assume its Embrace, extend, and extinguish. Its something Microsoft is know for and this worried me when they started to “Embrace” Linux. However, I don’t believe big tech can do much in terms of polluting open source and the fediverse.
I dont follow this much but I can see that these companies are investing into what they think the future could look like.
Might just be me…
I setup AdGuard DNS on the network I host my services on and made Tailscale use it as a second DNS. This let’s me access services using domain names. I’m sure you can do something similar with zerotier but I’ve never used it.
Also, it doesn’t have to be AdGuard DNS. Any DNS will be fine.
